ADJUSTABLE RIDDLE FOR WINNOWERS.

SEEGIFIGATION forming part of Letters Patent No. 697,324, dated April 8,1902.

Application filed March 6, 1901, Serial No. 50,102. (No model.)

T0 @ZZ whom it 77u63/ concern:

Be it known that we, CHARLES E. CrisrnnL and WILLIAM B. FAIL, citizensofthe United States, residing at Little River, in the county of Rice andState of Kansas,` have invented anew and useful Adjustable Riddle forWinnowers, of which the following is a specification.

Our invention is an improved shaking-shoe and adjustable riddle forthreshingmachines, the object of our invention being to provide improvedmeans for supporting the riddle in the shaking-shoe and for adjustingthe riddle to any required inclination while the shakin gshoe is inoperation.

Our invention consists in the peculiar construction and combination ofdevices hereinafter fully set forth and claimed.

In the accompanying drawings, Figure lis a perspective view of ashaking-shoe and adjustable riddle constructed in accordance with ourinvention. Fig. 2 is a vertical longitudinal sectional view of the same.Fig. 5 is a detail side elevation of the same. Fig. 4 is a diagrammaticlongitudinal sectional View of a threshing-machine, showing the sameprovided with our improved shakingshoe and adjustable riddle.

The shaking-shoe l is of the usual form or may be made of any desiredform and is suspended in the threshing-machine and vibratedlongitudinally thereinby the usual means, which are well known to thoseskilled in this art and form no part of our present improvements. Y-

A supporting and adjusting shaft 2 is disposed transversely across theshoe, has its bearings in the sides thereof and at one end projectsbeyond one side of the shoe, and is provided with a worm wheel orsegment 3, the same being fast on the said shaft. That portion of theshaft 2 which is between the sides of the shoe is angular, as shown, andthe said shaft supports apair of bars 4, which are longitudinallydisposed in the shoe and are of suitable length. Clips 5, which embracethe lower side of the shaft 2, are connected to the under sides of thebars 4, and thereby the latter are rmly secured on the shaft 2, and areadapted to be adjusted thereon longitudinally of said shaft to enablethe bars to be moved toward or from each other, as may be required toadapt them to engage the sides of screens or riddles which may vary inwidth. As here shown, the bars 4 are provided on their outer sides withflanges 6 and at their ends with flanges 7, said iianges 6 and '7bearing against the sides and ends of the frame of the screen or riddle,and hence maintaining the latter on the said bars. This construction ofthe said bars enables the screen or riddle to be readily placed thereonor removed therefrom, and it will be understood thatsaid bars supportthe said screen or riddie in the shoe, and as the said bars aresupported by the shaft 2 it follows that the inclination of the screenor riddle may be vaa ried as may be required by partly turning saidshaft 2 and securing the same when the screen or riddle is disposed atthe desired inclination.

A longitudinally-disposed adj usting-shaft 8 is journaled in suit-ablebearings 9 on one side of the shoe. The rear end of the saidadjusting-shaft projects beyond the rear end of said shoe, and said adjusting-shaft is provided at its rear end with a suitable handle 10, bymeans of which it may be readily grasped and rotated manually. At thefront end of the said adjustingeshaft 8 is a worm 11. The lat terengages the worm wheel or segment 3, and hence when the saidadjusting-shaft Sis turned power is communicated to the shaft 2, and thelatter is partly turned in its bearings and caused to adj ust the screenor riddle, as will be understood.

It will be understood from the foregoing that the screen or riddle maybe adjusted in the shaking-shoe while the machine is in operation andwhile the shaking-shoe is being vibrated.

Having thus described our invention, we claim- A shaking-shoe having ashaft 2 journaled therein,a worm-wheel on said shaft,a set-sh"aft havinga worm engaging said worm-wheel, supporting-bars attached to, andsupported solely by said shaft 2, said bars having side flanges 6 andend lianges 7 on their upper sides, and a removable screen or riddlesupported IOO our own We have hereto affixed our signatures in thepresence of two Witnesses.

on said adj ust-able bars, adapted to be lifted therefrom and engaged bythe flanges thereof, said bars being laterally adjustable on said shaftto adapt them to receive and support 5 riddles orsereens of VariousWidths, substan- Witnesses:
